Mater Dei High School of Santa Ana, Calif., completed the West Coast sweep Monday at the Spalding Hoophall Classic, using a dozen 3-pointers to beat DeMatha Catholic of Hyattsville, Md., 79-71 Monday in a battle between two of the premiere programs in the country.

DeMatha closed within four, 71-67, with a late run, capped by a huge dunk by Victor Oladipo, but Tyler Lamb scored in the paint and Max Hooper sank two free throws to hold off the Stags.

No. 13 Mater Dei followed the winning ways of Los Angeles public school Westchester, which defeated highly-acclaimed St. Anthony of Jersey City 55-51 earlier in the day.

“It’s definitely nice another California team came out here and won also,” said Lamb, a UCLA recruit who’s friends with Westchester’s Dwayne Polee. “It’s always nice to hear that.”
